Micro-resistivity imaging logging technology, as the main electrical logging technology in imaging logging technology, can provide high-resolution, large dynamic range micro-resistivity imaging of wellbore formation, mainly for crack identification, thin layer evaluation, sedimentary facies. Analysis and formation anisotropy evaluation are of great significance for geological evaluation of complex reservoir space such as carbonate rock and igneous rock, and its market demand is also increasing.
For a long time, the high-resistance imaging tool, a high-resistivity imaging tool, has been monopolized by large foreign logging companies. China Petroleum Logging Co., Ltd. actively tracked the development of foreign micro-resistivity imaging logging technology, carried out technical research on plate design and measurement methods, achieved major breakthroughs in core technical problems, and developed successful instrument prototypes. The trial, which resulted in the formation of 6 to 8 patents and know-how, broke the monopoly of foreign technology and will enable the localization of the technology and equipment.
Domestic imaging logging tools have successfully served overseas markets for the first time
On February 16, the micro-resistivity imaging logging tool (MCI) independently developed by China Petroleum Logging Co., Ltd. was successfully drilled in the PDT-26 well in Indonesia. The instrument obtained the well logging data once in the well, and the interpretation results have been approved by the explanatory experts. This is the first time that China has carried out technical services abroad by using advanced imaging logging technology independently researched and developed.
